Fair enough about the fairies and Latias, although Charizard Y definitely doesn't beat either one of them 100% of the time (although Bisharp does (at least the grand majority of the time), but this is about Charizard Y, not Bisharp, you can pair Landorus with Bisharp too), while Landorus at least has the option to deal more damage.
Also here's CBB Dragonite:
252 SpA Mega Charizard Y Fire Blast vs. 216 HP / 228 SpD Multiscale Dragonite in Sun: 63-74 (16.7 - 19.6%) -- possible 7HKO after Leftovers recovery
252 SpA Mega Charizard Y Fire Blast vs. 216 HP / 228 SpD Dragonite in Sun: 126-149 (33.4 - 39.5%) -- 20.9% chance to 3HKO after Leftovers recovery
64+ Atk Dragonite Dragon Claw vs. 4 HP / 0 Def Mega Charizard Y: 159-187 (53.3 - 62.7%) -- guaranteed 2HKO
64+ Atk Dragonite Extreme Speed vs. 4 HP / 0 Def Mega Charizard Y: 106-125 (35.5 - 41.9%) -- guaranteed 3HKO
And Dragonite can Roost. Also, Landorus can outspeed and 2HKO it with HP Ice, although I'd say that Landorus does have 4MSS and probably will be walled by Dragonite as well. Bisharp and Charizard can also both be beaten by EdgeQuake, which is a fairly common combination. A lot of the Pokemon that can check Landorus can also check Charizard Y, but Landorus has an option to beat those Pokemon 100% of the time whereas Charizard has to rely on prediction and has no move that will allow it to beat that Pokemon if it switches in while you use a move that it resists (and still be able to break very many walls at all, as it really needs Fire Blast, SolarBeam, and Focus Blast, and without roost it's way too easily beaten by toxic, being worn down, and stealth rock).
